LCTRANSFER

Calculate the redistribution of the forces stored in the removed elements onto the remaining static system The structural members to be considered (beam elements, springs) are assigned to this task by assemblies.

Note: The elements to be considered must be deactivated with the calculation task DEACTIVATE before.

Arguments

lc (load case)

Load case name (usually summation load case) which is taken into account for the redistribution (input without postfix)

The referred load case is the last available related to the time (start day) at which the calculation action LCTRANSFER is performed in the construction phase.

The results of the forces of the deactivated elements are taken from this load case and applied onto the structure. Then this load case is updated with the results of this redistribution.

lcsuffix (load case) [optionally]

Suffix for the load case defined in lc, which is used to create a load case containing the evaluated forces to be applied.

Example: lc = "SW-SUM", lcsuffix = "_removal" -> "SW-SUM_removal"

init [optionally]

Set this option to initialize (set to zero) the results of the considered (deactivated) elements.

Note: If the calculation task LCTRANSFER is called up by the task REMOVAL, the input of lc is omitted, since in this case the calculation of the redistribution is automatically performed for all automatically created summation load cases.

In detail this calculation task works as follows:

• All nodes of the deactivated elements which are still active in the reaming structure are detected (i.e. the nodes which the elements where connected to).
• The results at these nodes (results at the end of the originally connected elements) are taken from the defined load case lc and applied with a negative sign as a nodal load (considering any existing eccentricities).
• Optionally, this applied incremental force can be saved in a load case by providing the input of lcsuffix.
• The defined load case lc is updated by adding the load case results of the applied incremental load.
